摘要
隐伏采空区的探测已成为近年来研究课题,采用无人机搭载发射装置,高空平面布置探测线和测点,克服在陡峭的山坡难以布置探测工作,消除地形地貌及其它条件对探测工作带的误差。对已知空区的探测和分析,验证了该方法的有效性和精确程度,为后续其它探测提供了频率域区间和参数校正。研究表明:此方法具有适用性强、工作效率高和精确度高优点,是一种可用于隐伏空区的探测方法,分析过程中可以辨别采空区变形情况。
The detection of concealed goaf has become a research topic in recent years.In this paper,unmanned aerial vehicle(UAV)equipped with launcher is used to arrange detection lines and measuring points at high-altitude plane,which overcomes the difficulty of arranging the detective work on the steep hillsides and eliminates the detection error resulting from the topography,landforms,and other environmental conditionsin detecting working zone.By detecting and analyzing some known goafs,the validity and accuracy of this method is verified,and the frequency domain intervals and parameter corrections for other subsequent detections are provided.The study shows that this method has the advantages of strong applicability,high work efficiency,and high accuracy.It is a detection method that can be used in concealed goaf and the deformation of goaf can be identified during the analysis.
